compile a "Hello, world!" C program with both:
```
gcc helloworld.c -o test_normal
gcc -Wl,-z,now -fstack-protector-all helloworld.c -o test_bindnow_canary
```
running `./security-check.py test_normal` returns `test_normal: failed RELRO Canary`
running `./security-check.py test_bindnow_canary` returns nothing
